Engine device

An engine device comprising:

• an intake valve that causes a main combustion chamber in a cylinder of an engine to take in air;
• an exhaust valve that causes the main combustion chamber to discharge combustion gas;
• a main fuel injection valve that jets and burns liquid fuel in the main combustion chamber;
• and a gas injector that mixes gas fuel with the air taken in by the main combustion chamber,
• wherein a gas fuel pipe that supplies the gas fuel to the gas injector and a liquid fuel pipe that supplies the liquid fuel to the main fuel injection valve are disposed to be divided on both sides of a row of head covers arranged in a line, and wherein an intake manifold that supplies the air taken in by the main combustion chamber toward the intake valve extends in parallel to the row of head covers in a cylinder block, and the gas fuel pipe and the intake manifold are arranged on the same side of the row of head covers.
